RING-SPI NNING FRAME.

SPECIFICATION forming part of -Letters Patent No. 224,344, datedFebruary 10,1880.

' Application filedJnne 15,1878.

To all whom it may concern Be it known that l, THOMAS MAYOR, of the cityand county of Providence, and State of Rhode Island, have inventedcertain new and useful Improvements in Ring-Spinning Frames; and Ihereby declare that the following is a full, clear, and exactdescription of the same, reference being'had to the-accompanyingdrawings, forming part of this specification.

Figure 1 is a front view of a ring-spinning machine in'whioh the ringand ring-rail form a stationary fixture and the bolster and stepders.

rail are made to reciprocate so as to lay the yarn on the bobbin. Fig. 2is a cross-section of part of the machine, showing one ring, spindle,and bobbin, the driving-cylinders and the band for driving the spindles,as also means for reciprocating the spindles. Fig. 3 represents aspindle provided with a long cylindrical whirl.

spindle is made to reciprocate with the bobbin so as to lay on the yarn;and it consists in the peculiar construction and combination of parts,as will be hereinafter described and claimed.

In the drawings, a a are two'driving-cylinb is the driving-band. c c arethe spindles. d d are-the bobbins. e is the stationary ring-rail, and ethe stationary ring. f is a long cylindrical whirl extending thelengthof the traverse of the reciprocating spindle, the

band on this long whirl adjusting itself as the spindle is slowlyreciprocated.

m are secured,provided with anti-friction rolls m ,and the step-rail,bolster-rail, and spindles are reciproeated by means of the lever n, andthe weight coun terbalaneed by the Weight a. Motion is imparted to therails and spindles by the cam-arm o in contact with therotatingheart-cam p. p

The long cylindrical whirl presents a smooth surface throughout itslength for the engagement of the driving-band, which maintains itshorizontal position irrespective of the vertical reciprocations' of thespindle, and as the beltis not subjected to Variable twisting strains,the friction and wear on the same are materially lessened.

Having thus described my invention, I

' claim as new and desire to secure by Letters IEatent- The combination,in a ring-spinning frame, of a fixed ring-rail, traversing spindle, andtraversing step-rail and bolster-rail, a spindle-driving drum working infixed bearings,

and a plain cylindrical spindle-Whirl, which is fast on the spindle andthe axial length of which is equal, or thereabout, to the length oftraverse of the spindle, as and for the purpose herein deseribed.

THOMAS MAYOR.
